Write the common name for each of the following: a. CH 3 −CH 2 −O−CH 2 −CH 2 −CH 3

All right. Hi, everyone. So this question is asking us to provide the common name of CH three och two ch two ch two ch two ch three. Option A says methyl Buttal Ether. Option B says Ethel Beetle Ether. Option C does Methyl Pencil ether. And option D says Ethel Pencil. Et so let's go ahead and get started. The first thing I want to point out here is that in the structure provided we have one oxygen atom in between two carbon atoms or two ocho groups. Now this matches the general formula ror which is characteristic of an ether. So recall that the common name of an ether is generated by first listing the groups connected to oxygen in alphabetical order, followed by the word ether. So to the, to the left side of the oxygen atom is simply a one carbon chain or a CH three, which would correspond to a methyl group. And on the right side, if I go ahead and I count the number of carbons of the second all kill group, I can see that it is of in fact a five carbon chain. And so a five carbon chain treated as a substituent would be described as a pal group. So now these are the names that I would place in alphabetical order, followed by the name Ether. Now recall that if the ocho groups were identical, I would use the prefix dye to indicate that there are two of the same ocho group present. But in this case, that rule doesn't apply. Now because the M in methyl goes before the p in pal, the metal group is the first substituent I would list. So that's methyl por ether with spaces in between all three words. And so the common name of the compound provided is methyl pencil ether, which corresponds to option c the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found the South.

Textbook Question

Write the common name for each of the following:
a. CH₃−CH₂−O−CH₂−CH₂−CH₃

Verified step by step guidance

Step 1: Identify the functional group in the given compound. The structure contains an oxygen atom bonded to two alkyl groups, which indicates it is an ether.

Step 2: Break down the structure into its two alkyl groups. The first group is CH₃−CH₂− (ethyl group), and the second group is CH₂−CH₂−CH₃ (propyl group).

Step 3: Recall the naming convention for ethers. Ethers are named by listing the alkyl groups attached to the oxygen in alphabetical order, followed by the word 'ether'.

Step 4: Arrange the alkyl groups alphabetically. 'Ethyl' comes before 'propyl', so the name will start with 'ethyl' and then 'propyl'.

Step 5: Combine the names of the alkyl groups with 'ether' to form the common name. The common name for this compound is 'ethyl propyl ether'.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Alkyl Groups

Alkyl groups are derived from alkanes by removing one hydrogen atom, resulting in a functional group that can bond with other atoms. In the given compound, the presence of CH3− and CH2− groups indicates that it contains alkyl chains, which are essential for identifying the structure and naming the compound.

Ether Functional Group

An ether is a class of organic compounds characterized by an oxygen atom connected to two alkyl or aryl groups. The structure provided includes an ether linkage (−O−) between two alkyl chains, which is crucial for determining the common name of the compound.

IUPAC Naming Conventions

The International Union of Pure and Applied Chemistry (IUPAC) provides systematic rules for naming chemical compounds. Understanding these conventions is vital for accurately identifying the common name of the compound based on its structure, including the identification of the longest carbon chain and the functional groups present.
